Code-Alongs
Overview
Code-alongs are interactive coding sessions where you'll build projects alongside your instructors. These hands-on exercises will help you apply the concepts from your modules in a practical context.
What to Expect
- Live, instructor-led coding sessions
- Practical application of course concepts
- Problem-solving strategies and best practices
- Q&A opportunities with experienced developers
Code-Along 1: Single Source of Truth & Builder Pattern
In this code-along, you'll implement the Builder Pattern to create a configuration class for a web application. You'll learn how to handle complex object creation with many optional parameters while maintaining code readability.
What You'll Build
- A configuration builder for a web application
- Validation logic for required fields
- Method chaining for fluent API design
- Default values for optional parameters
Code-Along 2: Gradle & File I/O
In this code-along, you'll use Gradle to manage dependencies and build a Java application that performs file operations. You'll learn how to read, write, and process files efficiently.
What You'll Build
- A Gradle project with proper dependency management
- File readers and writers for various operations
- Data processing from file inputs
- Error handling for file operations
Preparing for Code-Alongs
To get the most out of your code-along sessions:
- Review the relevant module content beforehand
- Have your development environment ready
- Clone the starter repository when provided
- Prepare questions about aspects you're unsure of
- Be ready to type along - don't just watch!
After the Code-Along
To reinforce your learning:
- Review the completed code and add comments
- Try extending the project with additional features
- Share your work with peers for feedback
- Apply what you've learned to your sprint challenge
